Meanwhile, the processing unit can also receive and generate a second type of label at a position corresponding to the obstacle according to the heat and shape information of the obstacle around the vehicle body collected by the infrared camera group and the distance between the obstacle around the vehicle body and the vehicle body measured by the ultrasonic detector group, wherein the second type of label comprises contour lines, numbers and letters with striking colors in the embodiment. Specifically, the processing unit may determine the property of the obstacle according to the heat and shape information of the obstacle, and those skilled in the art know that the property of the obstacle is determined because the heat and shape information of a human body, an automobile, a utility pole, and the like are definitely different. Whereby the processing unit is marked with a contour line according to the nature of the obstacle in that the position of the obstacle is opposite. In addition, the processing unit marks corresponding numbers and letters corresponding to the positions of the obstacles according to the distance between the obstacles around the vehicle body and the vehicle body measured by the ultrasonic detector group. For example, if there is a pedestrian around the vehicle body 1 meter away from the vehicle body, the processing unit may generate a human-shaped contour line at a position corresponding to the pedestrian, and display "1m" on the upper side of the contour line, and when the contour line and the "1m" are displayed through the display unit, the driver may immediately find the pedestrian around the vehicle body 1 meter away. It will be appreciated that in other embodiments, microwave radars may be used in place of the ultrasound probe.
The display unit at least comprises a pair of augmented reality head displays (in other embodiments, the augmented reality head displays can also be augmented reality glasses) which are connected with the processing unit and can be worn on the head of a driver. The first type of label and the second type of label generated by the processing unit are displayed through the enhanced display head for a driver to observe. That is, when the driver wears the head-up display, lines having a conspicuous color corresponding to the edges of the road surface and the lane around the vehicle body, a contour line corresponding to an obstacle around the vehicle body, which can embody the nature of the obstacle, and numerals and letters, which embody the distance between the obstacle and the vehicle body, can be seen. Therefore, the driver can clearly see the surrounding situation of the vehicle body, can accurately avoid the obstacles and drive in the lane, and is particularly suitable for the low visibility situations such as night, rain, snow, heavy fog weather and the like. In addition, the auxiliary driving information is displayed through the augmented reality head display instead of a reflection projection mode, so that the problem that a display area is limited does not exist, namely the augmented reality head display can also completely display the auxiliary driving information, and driving safety is further guaranteed.
It should be noted that the augmented reality head display has a position measuring device for detecting the position of the head of the driver, and the augmented reality head display is used for displaying the driving assistance information corresponding to the position of the head of the driver according to the position of the head of the driver. The auxiliary driving information is the first type label and the second type label.
